By solving the given equation 20 + 0.44x = 19 + 1.69x we get x=0.8.
<h3>What is meant by an equation?</h3>
When two expressions are connected with the equals sign (=) in a mathematical formula, it expresses the equality of the two expressions. For instance, an equation in French is described as having one or more variables, whereas in English, an equation is any properly written formula that consists of two expressions linked by the equals sign.
Determine which values of the variables result in the equality to be true in order to solve an equation with variables. The values of the variables that must fulfill the equality to constitute the answer are known as the unknowns, together with the variables for which the equation must be solved.
Given,
20 + 0.44x = 19 + 1.69x
20-19=1.69x-0.44x
1=1.25x
x=0.8
Therefore, by solving the given equation 20 + 0.44x = 19 + 1.69x we get x=0.8.

Answer:
-7
Step-by-step explanation:
Answer:
The length of QS = 8
Step-by-step explanation:
From the above question:
Δ Q R S ≅ Δ T U V
Q S = 3 v + 2 , and T V = 7 v − 6 , enter the lengths of QS
Hence:
Step 1
We solve for v
QS = TV
3v + 2 = 7v - 6
Collect like ters
2 + 6 = 7v - 3v
8 = 4v
v = 8/4
v = 2
Step 2
Solving for Q S
Q S = 3 v + 2
v = 2
QS = 3(2) + 2
QS = 6 + 2
QS = 8
The length of QS = 8
Answer:
(a) 0.675
(b) 0.3
Step-by-step explanation:
(Probability of functional red)
(Probability of non-functional red)
(Probability of functional green)
(Probability of non-functional green)
(a) The probability the board is functional is the probability that the red and the green resistors are functional.

(b) The probability that exactly one of the resistors chosen is functional is the probability that either red is functional and green is not or green is functional and red is not.
